A microcontroller is by definition a is a computer on a chip. It includes all the necessary parts (including the memory) all in one IC. You just need to apply the power (and possibly clock signal) to
Latest Answer: hello sir, i am expect more details about microprocessor, because you was explained more briefly about microcontroller only. ...
Switching the CPU to another process requires saving the state of the old process and loading the saved state for the new process. This task is known as a context switch.Context-switch time is pure overhead,
DRAM is the Hershey's chocolate of readable/writable memory: it's not the best, but it's cheap, does the job, and is available almost everywhere you look. DRAM data resides in a cell made
Latest Answer: DRAM forms the Physical Memory of the PC. The process of recharging described in the earlier post is know as a Refreshing Cycle. ...
Waiting state
Latest Answer: processor:busy stateprocess:waiting state ...
Distribute the computation among several physical processors.Loosely coupled system – each processor has its own local memory; processors communicate with one another through various communications
Latest Answer: Distributed system in genral refers to n/w o.s in which various systems (computers) are connected to sharing some of resources like printer etc. Each system have own data (including files etc) and whenever access over other's system data is required FTP ...

Main memory: – only large storage media that the CPU can access directly.Secondary storage: – extension of main memory that provides large nonvolatile storage capacity.
Latest Answer: Primary is were the operating system and other files are stored which is usually the hard drive. Secondary is a second hard drive or a CD/DVD ROM or 3 1/4 inch floppy drive or any other type of device that stores data. * Primary storage is usually ...
diskcopy Java Thread States
->Selects from among the processes in memory that are ready to execute, and allocates the CPU to one of them.->CPU scheduling decisions may take place when a process:1.Switches from running to waiting
Latest Answer: Disk schedulers in current operating systems are generally work-conserving, i.e., they schedule a request as soon as the previous request has finished. Such schedulers often require multiple outstanding requests from each process to meet system-level ...
->Ensure that the system will never enter a deadlock state.->Allow the system to enter a deadlock state and then recover.->Ignore the problem and pretend that deadlocks never occur in the system; used
